Master the fundamentals of EKG interpretation and electrocardiography in this comprehensive 3-hour video lecture. Delve into the electrical activity of myocardial cells and its representation on electrocardiograms, exploring the significance of deflection degree, direction, and velocity in relation to cardiac tissue physiology. Learn about resting membrane potential, threshold potential, depolarization and repolarization mechanisms, and action potentials. Examine the electrical activity of the heart, including Purkinje cells and the conversion of cardiac electrical events to ECG patterns. Understand electrode placement, ECG machine operation, and the interpretation of ECG patterns, waves, segments, and intervals. Gain insights into the timing and duration of ECG components, and their clinical significance. Perfect for medical students, healthcare professionals, and anyone interested in mastering the essentials of electrocardiography.
